0 for all girls out there who want to do engineering, math and science. thanks so much of as always for watching. ac 360 starts live from moore, oklahoma. er republican, thanks. good evening, everyone. we have a lot to cover this evening, dramatic new developments in the boston bomb investigations. also, late developments here in moore, oklahoma. including word that six people had been listed as missing and now accounted for. five are alive. they made it. one of them did not. also, what we saw and the remarkable people we met while visiting an area hospital today. also for the first time getting an up-close look at the wreckage at the plaza towers elementary school. we begin, though, tonight with a chilling image you will ever see. an act of terror in england. a man with a meat cleaver, a kitchen knife, just seconds earlier on the streets of a london neighborhood, neighborhood, this man and an accomplice reportedly chanting alla akbar, god is great, hacked a man to death. the victim, a british soldier from a nearby post. police say the two men knocked him down with a car, descend canned on him with knives and cleaver and gun and dumped his body in the road. then almost, unbelievable, one of the killers approached onlookers and made a statement. watch. >> i apologize that women had to witness this today. but in our land, our women have to see the same. you people will never be safe. they don't care about you! >> he went on to say, quote, we swear by all mighty alla, we will never stop fighting you. he and his partner confronted police. prime minister david cameron sounded a defiant note. >> we have always beaten them back. we have done that through a combination of victim vigilance, security, good policing. but above all the way we have beaten them back is showing an absolutely indomitable british spirit that we will not be cowed, we will never buckle under these sorts of attacks. >> as i said, the attack -- the attack was brutal, horrific. joining us now with details, nick robertson in london. nick, this is really a stunning kind of terrorism. what is the latest we know about the victim and the man in custody? >> reporter: we don't have a name for the victim yet. he is believed to be an active service duty soldier. we have very few details about the two men involved. they both appear to be relatively young, early to mid 20s. described as afro caribbean, quite tall. beyond that, very few details. both being held in separate hospitals at this time. no indications yet, other than what they have said about where they might come from. but that is perhaps the biggest clue. their accents do appear to be very pronounced british accents, anderson. >> so, again, we don't know if they are british-born, raised in england. do we know anything about kind of the level of planning of this attack? >> reporter: well, the indications are, and this really frenzied attack that was utterly brutal and going through it for them would have been traumatic experience. the fact that they then stayed there for almost 30 minutes before the police arrived to take them on, and give statements, call on people at the side of the road to ask to use their cell phones to record statements is an indication they knew what they were going to do. they had waited outside the barracks, waited for the soldier. we don't know a specific soldier. attacked him, killed him and then paused and then went to people on the street to ask them to record their message. it clearly shows a level of planning. we don't know the extent of the planning. security services concerned enough to be upping security at all the army bases in london which is a clear indication they're concerned there may be a potential for more acts like this right now, anderson. >> that's incredible. so, wait. so they allegedly killed this man, brutally, and then asked passers-by to videotape them, to take pictures of them? >> reporter: they didn't run away. and all types of attacks -- of this nature, generally, the attackers will kill somebody, move on and try and get away from the police. we have seen this before in this style of what appears to be a radical islamist type of attack. that's the way they were defining themselves to the people there. the attackers would record a video before they go in for the attack. here, the men know, because they're waiting, they're going to be arrested by the police. and they know that this is their opportunity to get across their message. that does show that -- a brazen level of disregard for what they've done. disregard for their own security, as we saw when the police arrived, they were shot. anderson. >> and a desire to send a message and a desire to make a point, which is where the british government was so quick to label it terrorism. nick, appreciate it. we're going to talk to christiane amanpour later on in this hour. we want to get more details about this, how it compares to other attacks we have seen, not only in england, but elsewhere throughout europe. six previously unaccounted for people here in moore, oklahoma have been located. one of them, we know, has died, as i mentioned. there is no clear word yet whether that brings the number killed to 25. right now the official death toll here is 24. ten of whom, as you know, are children. the number injured now topping 350. and some of them are telling remarkable stories. first, though, i want to tell the stories that people who can no longer speak for themselves. tiwana robinson with the storm bearing down from inside a closet, called her daughter. she described her situation. she said "i love you." and the phone went dead. tawuana robinson was 45 and today we are getting more names of those passed. terri long worked at the faa, air safety specialist. terry long was just 49 years old. megan megan futrell riding the out the storm in the cooler of a 7-eleven. case futrell in his mom, megan's arms when he died. 4 months old. a lifetime of stories ahead of him. kyle davis was a rock of a little boy. his friends nicknamed him "the wall." got good grades in school, loved monster trucks. kyle was 8 years old, one of seven children who died at plaza towers elementary. antonio candlearia, leaves behind two sisters. nicholas mccabe is described as a vibrant 9-year-old, full of life, full of smiles, who loved legos. we met janae hornsby's dad. he called her a ball of energy and love. can't believe she is gone. neither can her cousin who tells her mom, i don't want to sound crazy, but she is going to call me. her dad still hopes that somehow his daughter may still be alive, but he knows she is not. the first thing people noticed about sydney marie angle was her eyes and smile. she loved softball, pitched her first game recently. she loved her dog, charlie. she loved her classmates at plaza to we ares and they loved her. sydney angle 9 years old. seven can kids died, ten in all. shannon quick, leaves behind two sons, 8 and 13 years old. they were all together when the storm hit. the 8-year-old was hurt, as well. so was his grandmother, shann shannon's mom, joy. we met the mom and listened to her story in the hospital in oklahoma city where she is recovering. she was sitting next to her daughter-in-law. how long did it feel like it went on for? >> 13 minutes, at least. >> were you able to speak to each other during it? >> i just remember hollering. asking god to keep us safe. but then it took the wall, the ceiling, and i could feel it suck the wall out from behind us. it felt like it was trying to somersault me, had me all up in a ball. and from there something hard hit me on the bottom of the foot. i remember that. i don't remember anything hitting my arm. >> did you lose consciousness? >> i may have for just an instant, because the first recollection i have is tanner, my oldest grandson, he was standing up. he -- the boys call me ma instead of grandma. i'm ma to them. he says, "ma, are you okay, ma, please be okay." and i don't know how long he had been hollering at me. but i was kind of able to push myself up. i can't move that arm, but i kind of used my elbow to push up. and then i saw shannon and i started yelling for somebody to come help. a person came over there and called 911. they couldn't -- it was so bad they couldn't even get ambulances up in there to help her. >> as soon as you saw her, you knew she was in bad shape? >> yeah. >> hole in the intestines. >> there was gas everywhere and a fire. i knew it was going to get blown up. >> were you able to talk to her? >> she kept saying she couldn't breathe. and i think her lungs were building up with fluid. she kept saying "tanner, jackson, tanner, jackson." and i told her they were okay, just to lay real still. she kept saying she wanted to turn over so she could breathe better. >> what did you say to her? >> to lay still so she didn't cause any worse injuries. >> when did you find out that she had passed away? >> the emt guy was oh over there. she had been holding on to his pant leg. he was standing next to her, and she had her fingers gripping his pant leg, and he kept talking to her. and all of a sudden her arm went limp, and he had taken some military guy had taken his shirt off and had that over her chest to kind of keep her warm and put it up over her face. kept telling them she wasn't gone, she was breathing. she wasn't. >> what do you want people to know about shannon? >> i think people that know her already know about her. she was so good. there's not a soul that didn't love her. >> a loving mother. >> she loved her kids. still so hard to believe, isn't it? thank you for taking the time to talk to us. i appreciate it. >> shannon passed away there on the scene in her family's home. she has two children, as i said, one of whom who is in intensive care at another hospital. a fund has been set up to help their family, not only in the immediate -- right now because they have no home, but also down the road with medical bills and the like. you can contribute by going to www.fundme.com/30 mh 60. www. www.gofundme.com/30mh60. we want to bring stories as much as possible. last night a viewer saw our interview with janae hornsby's dad, moved them deeply. they offered to pay for her funer funeral. we connected them with the family and thank them for their part. you can contact me on twitter @andersoncooper, i'll be tweeting in the hour ahead, although the service still spotty. a look at the devastation sat towers plaza elementary school. and breyerwood elementary school destroyed. you know that, as well. everybody made it out alive. we'll talk to the principal, just ahead. humans. even when we cross our t's and dot our i's, we still run into problems. namely, other humans. which is why at liberty mutual insurance, auto policies come with new car replacement and accident forgiveness if you qualify. see what else comes standard at libertymutual.com. liberty mutual insurance. responsibility. what's your policy?

>> we basically just surrounded the school and started running into different areas. some of this has been cleaned out. due to the search and rescue efforts. they're literally just climb oefing over debris. people were yelling for help, so pulling people out as quickly as possible. and that went on literally for hours. >> this was a hall of classrooms that led -- >> classrooms on each side. >> not connected, though. there was nothing? >> that was a classroom straight ahead. there was classrooms out here. you can see there's still tile. >> right. this is gone. >> this classroom is gone. >> these classrooms are all gone. >> more on the front side here too. anywhere we see tile. >> you can see the door leading into what was the classroom. >> back wall with the board. that's the front wall of the school there. >> front wall would have been right there, yes. >> is there a place in the school where people fared better? >> you can see where there are still walls standing up. obviously, that corner, the main part of the tornado came through this way. so this is the area that took the most as it went through this part here. so that's -- you can just kind of see where the walls are standing and where they're not. a lot of 460-something students. unfortunately, we did lose seven. but by looking at the damage, it's a miracle that we didn't lose a lot more. and none of this has been touched. this is what it looked like. there hasn't been tractors moving anything. this is how it landed. >> the people have been through, and that region will be certain there is -- >> this is what has taken so long. we had to go through all of this. and this goes for 15 miles the other way. >> 15 miles? >> of just like this. >> 15 miles just like this. >> 15 miles, yes. >> john king joins me now. to see it up close like that, it's just gone. >> the school was shaped like a u and essentially the two arms are gone and the flat crossbar, some of that is left. and that's where you had the one interior wall, the only piece left. and that will be the big debate. it's an older school. should it have had some kind of underground shelter, something more secure. if you're parents of one of the seven who perished, i'm sure your answer is yes. >> a lot of folks. i talked to the mayor last night and he said he didn't think just the economics of building either a basement or safe room or a shelter -- that there was going to be a ground swell of people wanting that to happen. >> the finances will be the debate going forward. and part of the debate will also be, anderson, on a full at a, they don't know how many were there at the time the storm hit. on a full day, 460 students in that building. how do you build a room big enough suspect most of them were survived. some will make that argument. it's an impossible argument to sell to the parents who lost their children. if you go through the entire neighborhood, it is just amazing. they have been shut off even to residents because they're just turning the electricity and gas back on today and they think they've got it shut off where they were supposed to but there is a risk of fire. but if you watch, there are cars there that belong miles away. and there are beds and, you know, and the school is full of beds and furniture from the nearby homes. vehicles to come from miles away. you get a sense when you go through, a lot has still been untouched. it's just one of those things, you see how wide it is. 15 miles. >> the other thing, i think teachers are heroes every day in schools around the country. but we saw so many just heroic actions by teachers at that school, and briarwood elementary. and other schools getting the kids to safe places and also staying with the kids and getting them through the storm. >> and if you see how deep some of the debris has been moved. because of the heroic first responders, said they heard screaming, cries for help. these are little kids crushed under the debris, classrooms crashed on top of them. the fact they moved so much to get people out but teachers able to protect the students. it is gone. it's ripped off. most of the school is ripped off the foundation. >> john, appreciate it. thanks. briarwood elementary, as i mentioned, here in moore was also destroyed by the tornltado. the video is equally as testify stating as the scene as plaza towers, but amazingly everyone at briarwood, students, teachers, staff, got out alive. shelly mcmillan is the principal at briarwood. she joins me now. >> hey, nice to meet you. >> nice to meet you. thank god. i mean, what you and your teachers did is extraordinary. i talked to some of them last night. how much warning did you have the storm -- that the storm was coming? >> well, we knew a lot -- we knew about it, just because we were watching the weather channels, monitoring that. and sirens went off. and we had been planning all day for the storm to come. and so -- >> when it actually -- >> an hour? >> when it actually hit, what thank you do? >> well, we were watching it come. and i was just praying that it would go a different direction. but it didn't -- or lift. but okay, it's coming. this is it. and so we had a few parents and teachers watching and tracking it, and everybody getting in their safe spot and off -- everybody went to their safe areas. they were already there, though. once the sirens went off, i had everybody in from the gym, from the portables, everybody was already in their spots. >> i talked to a teacher from briarwood last night. finish strong was the motto for her class. >> yeah, mrs. graham, yeah. >> and she did a great job of getting everybody in a closet, also other folks in bathrooms. and she was so proud of her students for the courage they showed during this. >> absolutely, yes. they were calm, and we practice drills all of the time. >> this is something you practice. >> all of the time, yes. at least monthly, you know. fire, lockdown, tornado. >> your school is a newer school. it's not a brand-new school, but it's newer than some of the other schools. and so it's built a little bit differently. >> yeah, it's a pod school. so they're not -- it doesn't have hallways. so they're each pod. >> do you hope that some sort of change occurs, that schools are able to build shelters? >> oh, i think that would be great. yes. there are so many we have to protect. i think it would be a great idea. i don't know how financially if that's possible or not. i'm not in that end of it, but, you know, from a parent point of view, from a teacher, principal point of view, that would be fabulous. >> you must be proud of your teachers. >> absolutely. amazing, amazing. they're veteran teachers, so they've all been there quite a while and they know the students. they've had several siblings. so they knew exac
